NOTES: Avon Tyrrell was designed to be a 'calendar house' incorporating 365 windows (to represent the number of days per year), 52 rooms (weeks per year), 12 chimneys (months per year), seven outer doors (days per week) and four wings (seasons).
NOTES: This drawing is one of a number included in Cockerell's album of house studies entitled 'Ichnographia Domestica', which was compiled in 1825 with later insertions.
